means for regulating the level to which the siphon will draw off the cream.

Other objects of the invention not specifically enumerated will become apparent during the course of the following detailed description when read in conjunction with the accompanying drawing which forms a part of this specification, and in which:

Figure 1 is a side elevational view of an embodiment of the invention shown in position in a milk bottle;

Fig. 2 is a view taken at right angles to Fig. 1;

Fig. 3 is a side elevational view with the siphon shown in charging position; and

a Fig. 4 is a perspective view of a connecting strap employed in the invention.

Referring now to the drawing in detail, wherein like numerals refer to like parts throughout the same, my improved siphon tube 5 comprises a single length of tubing bent upon itself to form two communicating legs 6 and 7. The leg 6 is adapted to extend down inside the neck. 8 of a milk bottle 9 and the leg 7 is adapted to extend downwardly outside of the bottle 9 as clearly shown in Figs. 1 and 2, the leg 7 being slightly longer than the leg 6.

The leg 7 is bent away from the leg 6 to provide a diverging portion 10 to clear the bulging side of the bottle 9. lhe end of the diverging portion of the leg 7 terminates in an outwardly extending open end portion 11 for the delivery of liquid from the siphon.

The leg 6 of the siphon which is preferably parallel with the upper portion of the 1931. Serial No. 538,828.

leg 7 extends down inside of the bottle 9 and is provided with a substantially hook shaped lower end comprising a laterally extending portion 12which extends at an angle from-the main leg portion Sand which terminates in I a substantially horizontal end portion'13,

formedby bending the tube back so asto intersect the center line of the leg 6 :of the siphon at substantially right angles. The open end 14 of the horizontalterminal por- A tion 13 preferablyextends the same distance 1 past the center line of the leg 6 to one side of the bend 1 5, connecting the lateral portion 12 and horizontal portion13 is ofiset to the other side.

Ametal strap 16, having an eye 17 formed at either end, eXtends between the parallel portions of the legs 6 and 7, said. legs being received in the eyes 17 of said strap,

The slide maybe frictionall'y adjusted up and down on the legs so that in addition to strengthening the siphon and protecting the bend 18 between the legs from breakage, the

strap also regulates the depth to which the intake portion 13 of the siphon may extend.

into the bottle. The strap 17 rests on the edge 19 of the mouth of the bottle while the cream is being siphoned off. 7 V

In operation, the leg 6 of the siphon is first inserted into the bottle as shown in Figs. ;,1;

1 and 2, the outer end 11 of the leg 7 is then closed with the thumb or finger and the siphon is then raised-and tilted to the position shown in Fig. 3, with the intake end 14 still immersed in the cream and with the;.

main portion of the siphon inclined downwaruiv at an angle from the rim of the bottle. As the trapped cream occupies the leg 6 from the end 14 to a point past the juncture of the lateral portion 12, the cream will;,-.

flow on down to the bend 18 when the finger is released from the end 11 and then back up the leg 7 toward the end 11 until it reaches the level of the cream in the bottle, thus completely charging the siphon with cream With the siphon thus charged it is returned to the position shown in Figs. 1 and 2 and the cream continues to flow as will be readily understood until the level of the cream falls below the intake end 14.

' out departing from the spirit of the invention a The strap 17 being vertically adjustable on the legs 6 and 7 makes the siphon particularly well adapted for the removal of cream from both pint and quart bottles and permits adjustment for removing just the right amount of cream regardless of the amount on top of v the milk in the bottle.

Although a preferred embodiment of the invention has been shown and described, it will be understood that various changes in the details of construction may be made withas defined by the appended claim.

I claim:

A substantially U-shaped siphon formed 7 from a length of tubing bent upon itself to provide a pair of communicating legs, the legs having a main bod portion substantially in the same plane with one leg being shorter than the other, the shorter leg being adapted to be disposed within a container, the longer leg being located externally of the container,

'said shorter leg having a free end portion located at a right angle to the plane passing through the main body portions of the legs and an angular portion connecting the free end portion with the body portion, the free end portion and the angular portion providing means for priming the siphon when the free end portion and angular portion having been submerged in a liquid in the container and the main body portions of the legs have been moved to a downwardly inclined position exteriorly of the container.
